State police said they believe Navarro shot Ponce in the back of the head, then killed himself. Police said one of the men lived at the home and the other victim was a friend.

Action 7 News has learned that one of the victims may have been dating the other's sister.

A member of Ponce's family found the bodies around 10 a.m., police said.

"I hadn't seen my brother or my boyfriend for a couple of days so I said, 'Let's go to my house and get with what they're doing,'" said Evelyn Ponce.

But when they walked in, Timothy Ponce Sr. said, "I opened the door and I seen them both laying there on the floor."

"My wife says, 'He's still alive.' So, we ran back over there and started CPR on them because he was still breathing," said Ponce Sr. "It looked like my son got shot in the back of the head and it looked like the other guy got shot in the head too."

The Ponces said their 16-year-old was clinging to life.

They called 911, but said when officers arrived they did little to help Timothy.

"They just let my brother die on the floor, you know, that's wrong," said Evelyn Ponce.

According to the Ponces, police showed up at the house with their guns drawn, ordered them to stop performing CPR and did not help Timothy at all.

"Nobody did anything. We were the ones trying to help him," said Evelyn Ponce.

But police said they were just following procedure, because they did not know if the scene was safe when they arrived.

Bosque Farms police said their officers were performing CPR on Timothy until paramedics arrived, but there was nothing they could do.

"I can only imagine the officers did go in with their guns drawn, seeing how it was a shots fired call. I do know that officers did administer CPR on the individual," said Chief Joe Stidham of the Bosque Farms Police Department.

Police recovered a gun from the scene, which has been forwarded to the crime lab for analysis. Autopsies will determine when the deaths occurred.
